Answer:
1) 19200- for Aarati 2) 17280- for Aakriti
Step-by-step explanation:
1. 16000/100*20=3200- THE MONEY WHICH ARE THE PROFIT,
2. 16000+3200=19200- THE PRICE for Aarati
3. 100-10=90 PERCENTS - the price for AAkriti contains from the price from Aarati
4. 19200*(90/100)= 17280- the price for Aakriti
The expression for the cost of the ABC Book Club is 2<em>x </em>+ 40. The expression for the cost of the Easy Book Club is 3<em>x</em> + 35. To find when the total charge for both book clubs is equal, the two expressions must equal each other. (<em>x </em>= the number of books read)
2<em>x </em>+ 40 = 3<em>x</em> + 35
Subtract 35 from both sides.
2<em>x </em>+ 5 = 3x
Subtract 2<em>x </em>from both sides.
5 = <em>x</em>
So, the total charge for each club is equal when 5 books are read.
Let the interior angle be x.
x/(180-x) = 13/2
2x= 2340-13x
15x=2340
x=156
exterior angle= 180-156=24
Number of sides=360/24=15
15-sided polygon
